Data classification

Here’s a broad definition of data types followed by the definitions of integer, float, and string: Data Type (Broadly Defined): A data type is a classification that specifies the kind of value a variable can hold and what operations can be performed on it. It helps the computer understand how the data should be stored, interpreted, and processed. -1. Integer (int): An integer is a data type that represents whole numbers without any fractional or decimal part. Examples: -3, 0, 42, 1000 -2. Float (floating-point): A float is a data type used to represent real numbers that have a decimal point. Examples: 3.14, -0.001, 100.0 --3. String (str): A string is a sequence of characters used to represent text. It can include letters, numbers, symbols, and spaces, and is usually enclosed in quotation marks. Examples: "Hello", "123", "OpenAI GPT-4" Let me know if you want examples in a specific programming language.

computer key board कीबोर्ड-  आधुनिक कंप्यूटर कीबोर्ड का इतिहास टाइपराइटर के आविष्कार से प्रत्यक्ष विरासत के साथ शुरू हुआ था । क्रिस्टोफर लैथम शोल्स ने पहले व्यावहारिक आधुनिक टाइपराइटर का पेटेंट कराया था।  इसके तुरंत बाद, 1877 में, रेमिंगटन कंपनी ने पहले टाइपराइटर का बड़े पैमाने पर विपणन शुरू किया।  तकनीकी विकास की एक श्रृंखला के बाद, टाइपराइटर धीरे-धीरे मानक कंप्यूटर कीबोर्ड में विकसित हुआ था ।  It is primary input device.used text base. there are different type of key board. Alpha numeric - It is use for Enter no. & text. Punctuation- Use forEnter addionational key (),  : ,;   Navigation- It use for move to cursor. Special - Perform some special task ( f5, f8). Window- Use for open window like start menu. Function- Use for help. (f2). Numeric- Use for enter numeric no. Modification- used for enter to the capital letter. PC / AT-  pc/at introduced by  I.B.M. It had 84 key. 101 key board replaced it. 101 key board- Introduced by i.b.m. in ...

I.R.Q. LINE OF CIRCUIT

 Interrupt Request (IRQ) Line in a Circuit An Interrupt Request (IRQ) Line is a dedicated hardware signal line used in digital circuits and computer systems to manage and prioritize interrupt signals. It enables peripherals, processors, and controllers to request attention from the CPU or microcontroller asynchronously, allowing efficient handling of time-sensitive tasks without continuous polling. Broad Explanation of IRQ Line in a Circuit: 1. Functionality: An IRQ line signals the processor that an external or internal device needs immediate attention. It interrupts the normal sequence of operations, temporarily suspending the current process to execute an Interrupt Service Routine (ISR). Used in embedded systems, microcontrollers, and computing devices to enhance multitasking and real-time performance. 2. Types of IRQs: Hardware IRQ: Generated by external devices like keyboards, mice, hard drives, and timers. Software IRQ: Triggered by programs or system calls to request specifi...
